Improvement in looms



JOHN MILLER, OF ELDIRIDGE, ILLINOIS.

Letters Patent No. 108,281, dated October 11, 1870.

IMPROVEMENT IN `LOOMS.

The Schedule refm'edto in these Letters Patent and making palrt of the same.

To all whom 'it may concern:

Be it known that 1JOHN MILLER, ot Eldridge,

y in the county of Edgar and in the State of Illinois,

have invented certain new and useful Improvement-s in Hand-Looms; and do hereby declare that the following is afull, clear, and exact description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon, making a part of this specification.

The nature of my invention consists in the coustruction and general arrangement of the parts ot ahand-loom, as will be hereinafter fully set forth.

In order to enable others skilled in the art to which my invention appcrtaius to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which- Figure 1 is a front elevation, and

Figure 2 a longitudinal vertical section of my looln.

Figure 3 is a plan view of the hatten and shuttleraee; and

Figure 4 is a front view of a'poi'tion of the headleframe, with mechanism for operating the same.

A represents the frame of my loom, at the front end of which, in suitable journal-boxes, is placeda shaft, B,.provided at each end with a crank-wheel, C, one or, both of which have cranks for turning the same.

lhe wheels C'O are, by means ot pitmen, D D, connected with the hatten E, so as to give it the neccssary reciprocating motion.

On the shaft Bv is placed a ruiter-pinion, G, which gears with a ruiter-wheel, H, placed upon a sha-ft, I, which runs at right angles with the main shaft B.

Upon the shaft I isa cog-wheel, J, which gears with another cog-wheel, K, placed upon a shaft, L, below and parallel with the former shaft.

Uu the rear end of the shaft L are keyed, or othcrwise secured, a series of wheels, a a, provided, at suitable points, cach with' a pin and friction-roller, h, for operating the hea-dle-ii'an'ies, M M, which are formed with curved inolines, as shown in iig. 4, on their under sides, for the rollers b b to work upon.

Y At the lower ends of the headle-fraines M M are cords, or wires, d d, connecting -with springs, e e, to bring them down again after thecams d have acted upon them to raise them up. y

N N are the picker-staffs, which are pivoted in a rocking bar, O, in front of the hatten, and are connected by a spring,f, as shown in fig, 1.

The upper ends ofthe picker-staffs N N pass through slots in the bot-tom of the shuttle-race 11, and by the motion back and forth of the hatten they are made alternately longer and shorter, or rather, the ends that project into the shuttle-lace arc made alternately longer and shorter.

0n the end of the shaft I is a crank, which moves two rods, y g.

Each of these rods is provided with an arm, h, which hysa strap, i, is connected with ythe pickerstail'.

The upper end of each picker-stati` is connected with a bar, It, said bars being placed one at each end within the shuttle-race, and having the shuttle-driver It attached to it. 1

There is also a pinyin., within the shuttle-race, for each picker-stati, and a cent-ral movable bar, a, bctween said pins.

Then the loom is in operation, the rods g g, with their connecting-straps i i draw the picker-stads alternately toward the ends of the shuttle-race. This is done when thel hatten is moving backward, so that the picker-staff, which is being drawn toward its end of the shuttle-race, will, as soon as the hatten moves forward again, slip under and outside of its pin m, and consequently -be retained there until the next stroke of the hatten backward, when the spring f will throw this staff suddenly inward, as soon as the upper end of the staff. clears the pin 1n.Y

By this sudden movement of the sta-if, the movable bar n Ais thrown violently against the upper end of the other staii, assisting in bringing it under and on the outside of its pin rm, to be. acted on in precisely the same manner.

The upper ends ofthe picker-staffs being connected with the bars k It, said bars and the shuttle-drivers follow the motions of the staffs, and in this manner the shuttle is thrown from side to side.

The cloth-roller, S, is operated by means of a lever, p, and spring pa-wl, r, which catches on a ratchet-wheel, T, at the end of said roller, the lever 1 resting upon a friction-rollcr, s, attached to van arm, t, on the hatten, as shown in tig. 2.

Having thus fully described my invention,

IVhat I claim as new, and desire to secure by Let ters Patent, -is- 1. In combination with the`headle-frames M M, constructed as described, and operated bymeans of the friction-rollers b b, on the wheels a a, the cords or wires l d, and springs c c, arranged and operating substantially as and for the purposes herein set forth.

2. The arrangement of the picker-stads N N, and the hatten E, the staffs being pivoted or hung in front of the hatten so as to be operated by the back and forward motion of the hatten, substantially in the manner and for the pnrposesherein set forth.

3. The arrangement of thepieker-stais N N, spring f, straps t 1'., arms vh. 71, and rods g g, operated by means of the crank on the end ofthe shaft I, substantially as and for the purposes herein set forth.

4. In combination with the above, the bars 7e k, shuttle-drivers It It, pins m m, and central bar a, all arranged and operating substantiailyas and for the purposes herein set forth. l

Iu testimony that I claim the foregoing, I have hereunto set my hand this 18th day of January, 1870.

JOHN MILLER.
